摘要
A series of NH2-SBA-15 were prepared via a aminopropyl-triethoxysilane to react with SBA-15 and characterized with N-2-BET, XRD, elementary analysis and FTIR and flavanone was synthesize via condensation between 2'-hydroxyphenyl methyl ketone and benzaldehyde catalyzed by the catalyst NH2-SBA-15. The microcalorimetric technique was used to study quantitatively the surface base sites of NH2-SBA-15 with intensity, number and distribution. It was shown that the reaction condition ( 550, 6, 1. 5) was the most compatible for synthesis of NH2-SBA-15.
